The essentials
Jump leads must comply with standard DIN
72553 (see c ab
l
e manufacturer's instruc-
tions). The wire cross section must be at least
25 mm 2
for petrol engines and at least
35 mm 2
for diesel engines. Note
● The v ehic
les must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected.
● The discharged battery must be properly
connected t
o the on-board network. How to jump start: description

– For vehicles with Start-Stop system: con-
nect one end of
the black jump lead X to a

le ground terminal, to a solid piece of
metal in the engine block, or to the engine
block itself ››› Fig. 79. 5. Connect the other end of the

jump
lead X to a solid metal component bolted
t o the en
gine b
lock or to the engine block
itself of the vehicle with the flat battery.
Do not connect it to a point near the bat-
tery A .
6. Position the leads in such a way that they cannot
c
ome into contact with any moving
parts in the engine compartment.
Starting
7. Start the engine of the vehicle with the boostin
g battery and let it run at idling
speed.
8. Start the engine of the vehicle with the flat batter
y and wait for 2 or 3 minutes until
the engine is running.
Removing the jump leads
9. Before you remove the jump leads, switch off the dipped be
am headlights if they are
switched on.
10.
Turn on the heater blower and heated rear
window in the vehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
11.When the engine is running, disconnect the lea
ds in reverse order to the details

Operation
Seat heating Fig. 147
In the centre console: front seats
he atin
g sw
itch The seat cushions can be heated electrically
when the ignition i
s
sw
itched on. The back-
rest is also heated in some versions.
The seat heating should not be engaged in
any of the following conditions:
● The seat is unoccupied.
● The seat has a covering.
● There is a child seat installed in the seat.
● The seat cushion is wet or damp.
● The indoor or outdoor temperature is great-
er than 25°C (77°F).
A
ctivate
Press the button or . Seat heating is
switched on fully. Adjusting the heating output
Pres
s the button or repeatedly until the
desired intensity level is reached.
Deactivating
Press the button or until all warning
lamps switch off. WARNING
People who, because of medications, paraly-
si s
or chronic diseases (e.g. diabetes) cannot
perceive pain or temperature, or have a limi-
ted perception thereof, may suffer burns to
the back, buttocks or legs when using seat
heating, an occurrence that may entail a very
lengthy recovery period or from which it may
not be possible to recover fully. Seek medical
advice if you have doubts regarding your
health.
● People with limited pain and temperature
thresho
lds must never use seat heating. WARNING
If the fabric of the cushion is wet, this can ad-
ver sely
affect the operation of the seat heat-
ing, increasing the risk of burns.
● Make sure the seat cushion is dry prior to
usin
g the seat heater.
● Do not sit on the seat with clothing that is
wet or d
amp.
● Do not leave clothing that is wet or damp
on the seat. ●
Do not s pi
ll liquid on the seat. CAUTION
● To av oid d
amaging the heating elements of
the seat heaters, please do not kneel on the
seat or apply sharp pressure to a single point
on the seat cushion or backrest.
● Liquids, sharps objects and insulating ma-
teria
ls (e.g. covers or child seats) can damage
the seat heating.
● In the event of smells, switch off the seat
heating immedi
ately and have it inspected by
a specialised workshop. For the sake of the environment
The seat heating should remain on only when
needed. Otherw i
se, it is an unnecessary fuel
waste. Front centre armrest
The centre armrest can be adjusted to various
l
ev
el
s.
Adjusting the centre armrest – To adjust the tilt, lift the armrest from the
star
ting position so that it is engaged.
– To return the armrest to the starting posi-
tion, remov
e the armrest from the upper
fixed position and lower it.

Checking and refilling levels
When the engine is running
A lthough the alt
ern
ator generates electrical
power, the battery can still become dis-
charged while the vehicle is being driven.
This can occur when a lot of power is being
consumed but only a small amount supplied,
especially if the battery is not fully charged
initially.
To restore the necessary energy balance, the
system will then temporarily shut off the elec-
trical devices that are using a lot of power, or
reduce the current they are consuming. Heat-
ing systems in particular use a large amount
of electrical power. If you notice, for instance,
that the seat heating* or the rear window
heater is not working, they may have been
temporarily switched off or regulated to a
lower heat output. These systems will be
available again as soon as sufficient electri-
cal power is available.
You may also notice that the engine runs at a
slightly faster idling speed when necessary.
This is quite normal, and no cause for con-
cern. The increased idling speed allows the
alternator to meet the greater power require-
ment and charge the battery at the same
time. Checking and refilling levels

Filling up Read the additional information carefully
›› ›
page 51
If the automatic filler nozzle is operated cor-
rectly, it will switch itself off as soon as the
fuel tank is “full”. Do not try to put in more
fuel after the nozzle cuts out, as this will fill
the expansion chamber in the fuel tank.
The correct fuel grade for your vehicle is giv-
en on a sticker on the inside of the fuel tank
flap. Further notes on fuel can be found at
››› page 243.
The capacity of your vehicle's fuel tank is giv-
en in ›››
page 51.
Vehicles with natural gas engines and hy-
brids
Every 6 months it is necessary to run on pet-
rol until the control lamp switches off and
then the tank must be refilled. This is neces-
sary to ensure that the system works proper-
ly, as well as the fuel quality required for driv-
ing with petrol. WARNING
Fuel is highly flammable and can cause seri-
ous b
urns and other injuries.
● Do not smoke when filling the fuel tank or a
canis
ter. Naked flames are forbidden in the
vicinity due to the risk of explosion.
● Observe legislation governing the use,
stor
age and carrying of a spare fuel canister
in the vehicle.
● For safety reasons we do not recommend
carry
ing a spare fuel canister in the vehicle.
In an accident the canister could be damaged
and could leak.
● If, in exceptional circumstances, you have
to carr
y a spare fuel canister, please observe
the following points:
– Never fill fuel into the spare fuel canister
if it is inside or on top of the vehicle. An
electrostatic charge could build up during
filling, causing the fuel vapour to ignite.
Danger of explosion. Always place the
canister on the ground to fill it.
– Insert the filling nozzle as far as possible
into the spare fuel canister.
– If the spare fuel canister is made of met-
al, the filling nozzle must be in contact
with the canister during filling. This
helps prevent an electrostatic charge
building up.
– Never spill fuel in the vehicle or in the
luggage compartment. Fuel vapour is ex-
plosive. Risk of fatal accident! » 241
